Answered vital questions
Q: How does neuroticism influence mood reputation?
A: People with psychotic traits struggle to recognize unfavorable facial expressions like fear and sadness, frequently exhibiting decreased amygdala activity and decreased attention to mental cues.
What function does cortisol serve in the recognition of physical emotions?
A: Oxytocin enhances social prominence by increasing attention to facial attributes (especially the eye ), improving feeling reputation, and modulating neural activity in key areas like the brain and prefrontal cortex.
Q: Does oxytocin-based treatments treat psychotic symptoms?
A: Although preliminary evidence points to oxytocin’s potential to normalize neurological and behavioral deficits related to psychopathy, especially by promoting empathy and reducing aggression, more specific, dimension-specific studies are required.
Summary: Psychopathy impairs the ability to recognize and respond properly to personal facial expressions, often disrupting compassion and social habits. A fresh assessment examines whether oxytocin, a neuropeptide known to foster social bonds, can make up for these inconsequentials.
Although there are no conclusive studies but, independent research on oxytocin and psychopathy suggests that there may be some encouraging, dimension-specific benefits. The results suggest that oxytocin may one day be used to enhance personal knowledge and reduce violent actions in people with psychopathic traits.
Important Information
- Factor 1 ( Interpersonal-affective ) and Factor 2 ( Lifestyle-antisocial ) traits are related to emotional detachment and decreased amygdala response, respectively, while Factor 1 ( Interpersonal-affective ) and Factor 2 ( Lifestyle-antisocial ) traits involve impulsivity and hyperreactivity.
- Oxytocin’s Effects: Intranasal oxytocin boosts feeling acknowledgement accuracy, eye-gazing, and neurological responses, especially to negative psychological faces.
- Medical Potential: Oxytocin may restore both under- and over-reactive neurological responses in psychopathy, probably boosting compassion and reducing aggression.

Psychopathy is a difficult and often misunderstood problem characterized by personal detachment, lack of empathy, aggression, and violent behavior.
These characteristics have a significant impact on social functioning and pose a significant risk to society as a whole, ranging from personal dysfunction to manipulative or aggressive behavior.
A recent scoping review provides an interesting look at how the neuropeptide oxytocin might improve these impairments, in particular by enhancing physical emotion recognition and modulating neural responses to aggression and empathy.
The assessment carefully examined studies on the effects of estrogen on these same methods as well as the psychosomatic methods of recognizing emotion in people with psychopathic traits.
Remarkably, no studies to date have explicitly investigated oxytocin’s effects on individuals with neuroticism using visual feeling recognition tasks.
Instead, the authors compiled data from 66 separate studies looking at these topics. Their findings suggest that the psychopathy’s effects are both real and remarkably dimension-specific, as well as the emotional recognition deficits.
Two Faces of Psychopathy
Psychopathy is frequently divided into two main categories by modern psychological tools. The first, which is called” Interpersonal-affective” ( Factor 1 or F1 ), has a lack of guilt or empathy, and is characterized by superficial charm, emotional detachment, and detachment. The second,” Lifestyle-antisocial” ( Factor 2 or F2 ), includes traits like impulsivity, poor behavioral control, and a history of criminal behavior.
These dimensions show different brain activity and behavioral responses to emotional stimuli. Individuals with the F1 trait frequently exhibit sluggish physiological responses to others ‘ emotions, particularly fear and sadness. Studies show reduced amygdala activation and diminished attention to emotional facial cues in this group.
F2 traits are in turn related to increased emotional reactivity, particularly when confronted with threat and anger, and are associated with reactive agressivity and impulsivity. It is crucial to develop targeted interventions by understanding these divergent patterns.
The Social Salience Hypothesis
Oxytocin has long been regarded as a “prosocial” neuropeptide that is associated with trust, bonding, and empathy. It has effects both centrally, through widespread brain receptors, particularly in the amygdala and prefrontal cortex, and peripherally, through systems involved in arousal and attention.
A compelling hypothesis—known as the” Social Salience Hypothesis” —suggests that oxytocin enhances the brain’s ability to assign importance to social stimuli, such as emotional expressions.
Intranasal oxytocin ( in-OT ) has been shown to increase activity in brain regions like the fusiform gyrus and the anterior cingulate cortex, all of which are involved in emotion recognition, as well as increase attention to the eye region of faces and improve pupil dilation ( a sign of arousal ). These behaviors correspond to the psychopathy deficits, particularly those associated with F1-related traits.
Psychopathy, Emotion Recognition, and Oxytocin: A Three-Way Interaction
The review draws attention to numerous studies that show how people with psychopathic traits, particularly those who are highly literate, struggle to recognize and interpret facial emotions, particularly fear, sadness, and disgust.
These impairments manifest in both physiological and behavioral measures, including pupil dilation, eye-gaze tracking, and amygdala activation, N170 amplitude, and other event-related potentials.
Interestingly, oxytocin appears to modulate many of these same markers—but in the opposite direction. For instance, oxytocin can increase N170 amplitude during the initial stages of facial processing and increase gaze toward the eye region, which is crucial for interpreting emotion. This convergence points to a potential therapeutic use for oxytocin, which might improve the ability to recognize emotions in psychopathy.
But the picture is more nuanced for individuals with F2 traits. These individuals frequently exhibit hyperactivity in the amygdala and other risk-sensitive areas, which is related to impulsivity and reactive aggression. In this situation, oxytocin’s effects appear to lessen overactive responses to fear and anger.
Several studies showed that in-OT reduced amygdala activation in response to angry faces in individuals with antisocial traits, potentially reducing impulsive and aggressive responses.
Oxytocin and Brain Modulation: Beyond Behavior
In non-psychopathic populations, functional MRI studies reveal that oxytocin administration controls activity in key brain regions involved in emotion processing and regulation, including the amygdala, anterior insula, and ventromedial prefrontal cortex.
These changes appear to promote prosocial behavior, increase emotional awareness, and reduce sensitivity to perceived threats. Oxytocin has been shown to normalize activity in these circuits in clinical settings like those in those with autism or social anxiety, enhancing social interaction and understanding.
Although only a few studies have directly evaluated the efficacy of oxytocin in people with high psychopathic traits, including those who have antisocial personality disorder ( ASPD ) are included, the results are encouraging.
For example, oxytocin has been found to reverse hyperactivity in the amygdala among violent offenders and improve emotion recognition in forensic patients. Oxytocin increased empathy and attention to emotional cues among youths with callous-unemotional traits ( an early marker of psychopathy ).
Implications and Possible Next Steps
Although evidence remains preliminary, the review paints an encouraging picture of oxytocin as a possible modulator of the social impairments seen in psychopathy. Notably, its effects appear to operate in the same neurophysiological pathways as those triggered by psychopathy, which suggests a well-matched mechanism of action.
However, there are still significant research gaps. To date, no studies have directly tested oxytocin’s effects on emotion recognition in adults with psychopathy using dimensional trait analyses. Given the heterogeneity of psychopathy and the possibility that F1 and F2 traits may respond to treatment differently, this is a crucial oversight.
The authors recommend that future studies use both behavioral and physiological markers ( e .g., fMRI, EEG, eye tracking, and pupillometry ) to integrate oxytocin administration with facial emotion recognition tasks in populations with various psychopathic traits. Such studies could illuminate whether oxytocin’s benefits are trait-specific—and whether it holds promise as a targeted therapy for this difficult-to-treat condition.
Conclusion
Neuroscience, psychology, and society are in a formidable position to overcome psychopathy. Its multifaceted dimensions have a significant impact on how we perceive, feel, and behave in ways that impair human connection and empathy.
This scoping review suggests that oxytocin—a molecule traditionally linked with love and trust—might hold the key to improving social functioning in those with psychopathic traits.
Oxytocin might pave the way for novel, dimension-specific interventions in psychopathy by improving emotion recognition and modulating the neural systems of empathy and aggression.
What was once perceived as an untreatable disorder may one day become more manageable and more understood thanks to targeted research and careful clinical application.

” Psychophysiology of facial emotion recognition in psychopathy dimensions and oxytocin’s role: A scoping review” by Sara Ferreira-Nascimento et al. ONE PLOS ONE
Abstract
A scoping review of the psychophysiology of facial emotion recognition in the dimensions of psychopathy and oxytocin’s role
Psychopathy is characterized by social impairments that hinder effective societal functioning.
It has two main dimensions:” Interpersonal-affective” and” Lifestyle-antisocial,” each linked to distinct patterns of traits and central and peripheral neurocorrelates, particularly those relating to social salience and oxytocin function.
In this review, we synthesized and systematically identified the evidence from studies that examined the psychophysiological correlates of emotion recognition across different psychopathy domains.
However, as no such direct studies were identified, we instead compiled and analyzed research examining these variables separately.
66 articles were retrieved from a scoping review that looked at studies reporting on psychopathy or oxytocin in relation to facial emotion recognition.
We discovered distinct emotion recognition outcomes for different psychopathy dimensions, some even having opposing neural activity in response to emotional expressions, particularly those that are negative valence, as measured by neuroimaging, electrophysiology, eye-gazing, and pupillometry.
Oxytocin presented suggestive positive/compensatory effects on social salience, enhancing emotion recognition, and increasing pupil dilation, and eye-gazing towards faces, and decreasing brain activation towards negative emotions.
This review makes it absolutely necessary for future studies to examine how oxytocin and psychopathy interact with one another in order to bridge the gap between the two fields of study.
These efforts could lead to the identification of dimension-specific psychopathy biomarkers and targeted psychopathy treatments.
